Abstract Geogas survey performed in the Xinchang gas field shows that there exist obvious anomalies of nano-particle metal elements over the gas field. A comparative analysis of integrated soil geochemical exploration reveals that more than twenty nano-particle metal elements such as Ba, Cd, Cu, Mo, Zn, P, V and Ni have common response over the Xinchang gas field and in soil. Characteristics of organic geochemical indices over the Xinchang gas field are basically identical with those in geogas and in soil. Under certain conditions, geogas survey is somewhat promising in the prospecting for natural gas accumulation and the delineation of gas field.
